[ANN] Technobit HEX8A1 -240 GHs Coincraft A1 board- Finished production

[loshia]

Shame they have sold out the pre production run. I was interested in one. If anyone is looking to sell one at a fair mark up i would be interested.

March batch is available with reduced price. You can get one from there. But the price and roi does not bother you right?
Any way there will be enough guys with board in hand after a couple of days and you can get one with reasonable markup. However i am not selling mine

[loshia]

so I just received 3 boards today.

I opened one board to check it and one fan is broken on the edges and some nuts are missing to keep the fans on the board....it is not a deal breaker, but the nuts should have been there

I will test the boards in the evening with my less powerful 40A PSU (still waiting on my new ones).
How do I have to set clock and voltage? Or should I just try to decrease the voltage until it is stable?

You can set all via web of tplink or you can read changelog all settings are inside. A friendly advise. DO NOT CONNECT MORE THAN ONE BOARD TO 40 AMPS. NEVER! 40 amps at at the edge. Magic PSU smoke is very close

[dozerz]

im also interested in a board if any receivers are looking to sell theirs.

yes I wouldn't connect 2 boards 2 one PSU  , already got me additional PSUs for each board
I guess the changelog is in the download folder for the new tplink image right?...I will download the new image in the evening
I really hope it will work this time and that I don't have to many dead chips(or cores) again

I did see the pictures you had only one PCI-E 6-Pin connected! I was surprised 40A didn't melt it. 
A lot of multi rail PSUs (Platimax 1500W) have 30A rails I assume 2x 30A rails will be fine?

Thx Zich  
Only 2 days of shipping, I was astonished!

I will keep you posted how they work

Changelog is inside the archive with cgminer patch
The best setup will be a tplink and board powered from one psu 650-700W at least 45A  12/5V - do not mix psu's grounds. Powerful PSU's 85+A are expensive and does not worth the money. if you have 85+A on a single pSU you can connect two boards to tplink + HUB. Never mix grounds. that is my way 0% problems

More than fine Gator. in your case underclock/undervoltage even one can be fine. Just measure it if you can but on 12V rail not at the wall

This is my tool for measuring 12V rail current usage

hey it is an expensive one my is up to 10A and completely useless for hex8

Yeah  , since i am ex  service engineer, i can't help to use good quality one

Shame they have sold out the pre production run. I was interested in one. If anyone is looking to sell one at a fair mark up i would be interested.

March batch is available with reduced price. You can get one from there. But the price and roi does not bother you right?
Any way there will be enough guys with board in hand after a couple of days and you can get one with reasonable markup. However i am not selling mine

I am just looking to collect different types of hardware. If nobody can give me a fair offer soon I will just order for march.

Thanks

I would just hang fire. Someone might get 3x and realize they don't like the noise of 6x Sunon 4500rpm fans!
Someone on the TerraMine thread asked what their noise was like, the reply was, "loud enough your wife will leave you if you don't switch it off".
Well Sunon 4500rpm are that noisy too!

Unless you leave enough space between wife and fans Or you leave the wife first
Apart of the jocks they are noisy and dangerous. I was thinking gator is not right about it but in fact he is.
Watch it Gator. These ones are even more dangerous compared to previous ones
In general you can live without a finger or two but what bothers me much is the electricity. So kids and wife's are forbidden! that is why I keep my stuff locked always and it is only me who goes there. That is what all of us should do to be able to enjoy our families. I have 15 Kw in my room wires everywhere. A single wrong move can cost a lot

LOL, you make my imagination goes wild by saying new one more dangerous 
Can't wait to see what kind of heatsink & fan upgrade   

[Gator-hex]

I was a bit annoyed myself with missing the end of the Feb batch.

I don't like the new ordering system, I preferred it when you could see every item counting down, had no idea it was close to ending.

But I don't want to risk the March batch with Bitfury 2 on the way either, no idea the price/specs, but Punin seemed very confident!

So even if you missed the Hex8A1, cheer up, we can look forward to seeing what Marto can do with the Bitfury 2 chips in March!

That one Fan on the top is EXTREMELY noisy


Anyway, i flashed tplink with the newest image, but cgminer won't start, it is not even in the showing up as a running process.

It will get recognized as HEX16A


error message in cgminer api log:

Code:

[Firmware Version] => 20140208
cgminer: 3_12_3_e447b69
Socket connect failed: Connection refused

any guesses?

Set default to hex8 int the web and do not be angry it will work just a little bit of reading.
Post all startup options voltage clock and so on. Fill all blanks in the web cgminer configure using defaults do not leave nothing blank
Do not forget to set user pass of tpli k if it is fresh install before that it is not getting any of your setings
User pass set them dude
